Application filed May 7, 1908. Serial No. 431,299.

To .ol/ 'w/imn, it may concern:

lie it known that l, ALVIN C. McCoun, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improven'ients in Car-Axle-B0x Lids; andI do hereby declare the followii'lg to be a full, clear, and exactdescription. of the invention, such as will enable others skilled in theartto which it appertains to make and use the same.

My invention has for its particular objectto improve the cons ructionand operation of car axle box lids that are arranged to open and closeby a combined or resultant swinging and sliding movement; and to theabove ends the invention consists of the novel devices and combinationsof devices hereinafter described and defined in'the claim.

One type of lid, mounted as above indicated, is disclosed and claimed inmy prior Patent #839,871, issued of date January 1st, 1007, and anothertype thereof is disclosed and claimed in the prior patent to \VilliamGwDunham #803,155, issued of date October 31, 1905, and both entitledCar axle box lids. In the accompanying drawings I have illustrated myinvention as applied to a lid of the character disclosed and claimed inthe said Dunham patent. In these drawings, like characters indicate likeparts throughout the several views.

Figure 1 is a view in outside face elevation, with some parts brokenaway, showing box lid applied to a Journal box. Fig. 2 is a sideelevation of the said box and lid, some parts being broken away; andFig. 3 is a vertical section taken on the line 00 of Fig. 1, some partsbeing broken away.

Except as hereinafter cohstruction ofthe lid drawings of the present.application is substantially like that disclosed in the said priorDunham patent abor e identified; and this construction described is asfollows: The numeral 1 indicates an axle box of standard constructionand which, at its upper portion, adjacent to its mouth 2, is formed witha heavy hinge lug 3 having an elongated guide bol shoulder 5. Laterallyspaced bearing lugs 6 project outward from the hinge lug 3 and pointedout, the illustrated in the are shown as formed with seats 7 for apur-'8, on its inner face against the face of the t passage 4 and a lock.

pose which will presently appear; The lid 8, which is preferablyconstructed of. malleable iron, is formed with a central pocket 9 thatbulges outward. and upward to clear the lugs 3 and 6. At its upperportion the lid 8 is pivotally connected to the hinge lug 3 by a hingebolt 11 that is passed through the elongated bolt passage 4. The upperedge 12 of the pocket. 9 normally engages the lock shoulder 5 of the lug3. On opposite sides of the lid 8 is shownas provided turned lockflanges 13, and the lower portion of said lid is formed on its innerface with :1 depending lock flange 14. The said lock flanges 13and 14are the lid is closed they are engaged, respectively, with lock flangesor ribs 15 and 16, respectively, formed on the upper and lower portionsof the mouth of the box. The lid below the pocket 9, has an integrallycast or otherwise rigidly secured perforated bearing lug 17. 'lhe stemof a T-bolt 18 Works loosely through the perforated lug 17 with itstransversely ex tended head 18 pivotally mounted in the seat 7 of thebearing lug 6. This bolt 18 is preferably formed near its upper end witha fixed collar 19. A coiled spring 20 SH!" rounds the stem 18 and iscompressed between the collar 19 thereof and the bearing lug 17 on thelid, and exerts a pressure tending to hold the lid in a closed position,as shown in Figs. 2 and3, and against upward sliding movements on theface or mouth of the box. Nevertheless, in practice it has been foundthat, under the severe and constant jarring due to unevenness in thetrack, the lid will be causedrto vibrate even against the tension of thespringQO. This vibration seems to be against the direct line of strainof the spring but at all times along the face of the box. Otherwisestated, the spring seems to hold the lid pressed box but to yieldsufiijars to permit a slidwith downwardly clently under the said ingvibration of the lid on the face of the" box. Substantially the samestatement is true in respect to the lid disclosed in In said priorpatent above identified. A. sliding movement of the lid on the face ofthe box is not necessary either in opening or closing the lid, but onthe contrary, com bined or resultant outward swinging and upward slidingmovements in opening the 110 pocket 9 the upper edge of the so disposedthat Whenlid and combined or resultant downward hut'preferably they arelocated within the box. The stop lugs on the box are indicated by thenumeral 21 and they are shown as cast integral with the sides of the boxadjacent to the face or mouth thereof and are I located slightly abovethe lock flange 16 of l the said box. The cooperating lock lugs or 1surfaces on the lid are indicated by the nul meral 22 and they are shownas cast integral 1 with said lid and are located but slightly l abovethe lock flange 14, and are so spaced laterally that they aline one witheach' of the stop lugs 21. As clearly shown in Figs. 2 and 3, thesecotiperating stop lugs 21 and 22 positively prevent sliding movements ofthe lid on the'face oi the box, but, nevertheless, permit the lid to beopened by an upward swinging and sliding movement and permit the lid tobe closed by a downward swinging and sliding movement. hese lcotiperating stop lugs or surfaces add l nothing to the cost of the boxand at the same time eiiiciently accomplish the purpose of thisinvention as above set forth.

From what has above been said it will, of course, be -understood thatthe cooperatingv stop lugs or surfaces on the box and lid .t'orpreventing sliding movement of the lidon the face of the box may beapplied generl ally to lids that are mounted to open and l close by acombined orresultant swinging and sliding movement, from which state--ment'it of course follows that the said lugs will be serviceable whenapplied to the corn struction disclosedin my said prior patent. aboveidentified.

In the introductory part of the speoifica- 1 denies 05 this patent mayhe obtained for five cents located either interior or exterior of thebox K ment. of a tion it has been stated that this invention relatesparticularly to car axle box lids that are arranged to open and close bya combined or resultant swinging and sliding; movement. In the'lidsspecifically referred to, this combined sliding and swinging movement isprovided for by a hinge joint particularly designed to allow such moremerit. This same resultant or combined sliding and swinging movementwill 'fre quently take place in a lid connected by an ordinary pivot orhinge connection, due to play between the bolt. and lugs or similarparts of such hinge. Hence, it will be understood that the coiiperatingslop shoulders or surfaces on the'box and lid in! preventing slidingmovement oi. the lid when the lid is closed may be used to ailiuuhigu inconnection with any lid which would otherwise be capable of more or lesssliding movement on the face oi the box when the lid is closed.

What I claim is:

The combination with an axle bot; and a lid hinged thereto tor aresultant swinging and sliding movement. said lid having interlockinengagement. with the box under said resultant sliding and suine ing'umrcyielding thrust device arraugml to react against said lid and against allXlll base oi resistance on the box and urmngrrrl to exert a forcetending to hold the lid closed, a pair of stop lugs located on the innersurfaces of each side ot the box :uljacent to the face and near thelower por tion thereof. and stop lugs on said lid cugageable with thestop lugs on said box to hold said lid against. sliding movements on theface of the box when said lid is \"lum l. substantially as described.

In testimony whereof I ailix my signature in presence of two witnesses.
